Decoding control apparatus for decoding predictive encoded data. A picture detector determines the fewest possible pictures which must be decoded first before decoding a picture which are to be displayed after an edit point. A start-point finder for finds the start point for decoding the fewest possible pictures determined by said picture detector even though those fewest pictures are not to be displayed. A plurality of decoders decode the encoded data in picture units, on the basis of the start point. A picture obtained by the decoders is selected on the basis of the edit point and output.

A recording-and-reproducing apparatus for reproducibly controlling data recorded on a recording medium includes: a device configured to acquire control information required for reproducing the data when the data is recorded; a device configured to control operations during the period from the start to the end of recording data on the recording medium. The apparatus further includes a device configured to determine whether a recorded file of the data exceeds a predetermined limit of a storage capacity of a file system in the recoding medium and sequentially generate a subsequent recorded file upon exceeding the limit. Moreover, the apparatus includes a device configured to generate a single recording-and-reproducing unit during the period on the recording medium indicated by the control device based on a plurality of recorded files upon exceeding the limit; and a device configured to update the control information by recording the single recording-and-reproducing unit on the control information.

There is provided a recording device for generating and coding metadata, the recording device including a metadata describing part for describing the metadata; and a coding part for coding the metadata described in the metadata describing part in a binary format, and generating coded data; wherein the metadata describing part describes alternative information for embedding alternative data to the coded data when data is not present for a non-essential item in the metadata; and the coding part performs coding with the alternative data embedded when the alternative information is described.

Recording device, recording method, computer program, and recording medium

If a recording rate of data is close to a writing rate on a recording medium, recorded data is externally transmitted. The problems are solved by: an efficient separate use of data in a buffer and read out data; and the use of low resolution data. As illustrated, the 0th to third low resolution data to be transmitted are not read out from an optical disc because the data remain in a buffer at the time of transmission. Instead, the buffered data is transmitted. When the fourth low resolution data is to be transmitted, the fourth to sixth low resolution data are read out from the optical disc for transmission because the data have already been erased from the buffer. The present invention is applicable to, for example, a disc recorder.

Recording/reproducing device and method, recording medium, and program

A shortest cut duration is a minimum required period between an edit point set on a stream of pictures such as an MPEG stream and the next edit point set on the stream. Restrictions are made on the shortest cut duration lenient in editing the stream. A controller detects each edit point set on the stream and identifies the fewest possible pictures which are not to be displayed but must be decoded first before decoding a picture to be displayed after the edit point. Then, the controller finds a start point representing the timing to start decoding the fewest possible pictures. Subsequently, the controller controls decoders to decode the stream in picture units on the basis of the start point, and controls a switcher to select one of outputs of the decoders on the basis of the edit point.

Predictive encoding and data decoding control to decode fewest possible pictures

In recording information, meta data defined in SMPTE 298M and 335M, buried in video and audio material signals to be recorded to a magnetic tape () are extracted, the thus extracted meta data or meta data generated from information other than the material signals, are written to a contactless memory tag (), whereby it is made possible to acquire meta data about material signals recorded in a recording medium without actual reading of the material signals in the recording medium and use the meta data for search, validation, etc.

Information recording apparatus and method, and information recording system

A data processing method is disclosed which involves storing on an optical disk main line data as video data and low-resolution data, the latter data corresponding to the main line data but having a lower resolution and a smaller data amount than the main line data. The main line data and low-resolution data are read and decoded individually. The decoded result of the low-resolution data is selectively output until preparations for outputting the main line data are found completed. Once the preparations for outputting the main line data are complete, the decoded result of the main line data is output selectively.

An EPL maker () is composed mainly of editing terminals (), () and () each reading and decoding each of highly compressed sub materials to produce a material data and make an EPL while displaying, on a monitor, a video based on the material data. The EPL includes identification information for identification of a material used in editing and a format declare state for defining a format of at least a certain material. The EPLs made by the editing terminals (), () and () are stored into an EPL storage unit (). The EPLs stored in the EPL storage unit () are read by an edit controller (). The edit controller () makes an edit control signal based on the EPLs, and supplies the signal to a content maker (). Thus, an editing can be executed with having not to pool the materials once on hand and with labors and costs.

Data processing apparatus and data processing method

High bit-rate data and low bit-rate data for the same material are recorded in time division. Meanwhile, the recorded low bit-rate data is read out so as to be used for verification or time-shift playback. In a time-shift playback process, a plurality of tags, each tag containing low-resolution data, is read out at a time so that the read out low-resolution data are played back within excessive time generated by successively recording a plurality of cartons. For example, five cartons corresponding to an input video signal for 10 seconds are successively recorded. Within the resulting excessive time of 1.6 (=5&#xd7;0.32) seconds, five tag are successively read out so as to play back the low-resolution data for the reproduction time of 10 seconds. The present invention is applicable to a disc recorder.
